MediaRecorder start failed: -38

Question

i searched to check if this question is no dup , i see some has no answer and others did not help.

this is my code :

private void startRecording()
{         


        

Answer 1

In my case that error (MediaRecorder: start failed: -38) was appearing after switching to second camera when I forgot to release MediaRecorder during closing (first) camera:

mediaRecorder?.release()
mediaRecorder = null

Answer 2

Found the solution , it appears i had some other service in the background which is using AudioRecord and uses the mic as well.... so thats the -38 :)
